The frustrations of beginnings

So I want to get this up and going, but the thing is I can't figure it out. Like for instance, how do I change the header that I put up there at the top??? How do I post photos without losing my message? I have spent yet another hour with the logisitics of this thing. Perhaps I will find these things out sooner than later, most likely when I am not quite so brain-tired, and when I do it will surely be more representative of me :) With that, good night. For real this time.
